My first impressions of this mask are very favourable. Unfortunately, I haven't been able to use it because I wear glasses and the arms prevent the mask from sealing. Perhaps I should have thought of this.
My other concern is how the clear plastic will react to the solvents in many spray paints. If over-spray sticks or solvents make the plastic go cloudy, the mask starts looking like almost a single-use product. The mask is supplied with a clear, thin plastic film to protect it from minor scratches, so perhaps applying a new one of these after each use would solve the problem (if indeed it is a problem). A pack of disposable sheets of film would be needed.
